Abstract:
A fast convergent formula for the interactional energy between two parallel plates at constant surface potential and constant surface charge is derived by a simple method of the series expansion, and the numerical result of only the first five terms of the series is excellent for the dimensionless surface potential of colloidal particle y(0)< or =4.
